According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food?   A. The host cell would have been poisoned if it had digested the engulfed cell.   B. The host cell was able to survive anaerobic conditions with the engulfed cell alive.   C. The engulfed cell provided the host cell with CO2   D. The engulfed cell provided the host cell with ATP.   E. The engulfed cell allowed the host cell to metabolize glucose

Viral Replication

The virus is acellular and considered non-living outside the host cell. The replication of the virus occurs only inside the living cells. Only a few genes are present in the smallest virus, whereas many genes are present in the largest virus. These genes encode specific viral proteins.
